WILLIAM BANWARTH, OF GARY, SOUTH DAKOTA.

ACETYLENE-GAS GENERATOR,

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application iled January 3, 1912. Serial No. 669,203.

To all whom it may concern.'

Be itknown that I, VILLIAM BnNwAR'rH, a citizen of the United States,residing at Gary, in the county of Deuel and State of South Dakota, haveinvented certain new and useful Improvements in Acetylene-GasGenerators, of which the following is a specification.

My improved generator is especially adapted for use in garages and otherstations for the purpose of charging small tanks with acetylene gas tobe carried on automobiles.

The object of my invention is to provide an acetylene gas generator fromwhich charges of gas for small tanks may be drawn.

A further object of my invention is to provide means for varying thepressure of the gas in the small tanks; and with these and other objectsin view, my invent-ion consists in the parts and combination of parts aswill be hereinafter more. fully setfort-h.

The drawing is a vertical central section of an acetylene gas generatorembodying my invention, parts being in elevation.

1 represents a cylindrical tank or generating chamber having ascrew-threaded cap 2 and a screw-threaded base 3. The cap 2 is providedwith a safety valve 4 of suitable construction and a centralscrew-threaded opening 5 into which a screw-threaded cap 6 is adapted tobe secured. The base 3 is, as stated, screw-threaded to the tank 1 andis provided with supporting legs 7.

S is a drain or blow-ott valve in the base 3.

9 is a relatively long carbid container suitably perforated to admitwater 10 from the tank 1. This carbid container is divided into a seriesof chambers by means of the partitions 11 to prevent moisture frompassing by absorption from one section of the magazine or container toanother. The chambers between the partitions 11 in the container 9 areadapted to be filled with carbid 1Q, as clearly shown in the drawing.The carbid container 9 is supported at the bottom in the tank 1 onstandards 13, said standards being adapted to fit snugly againstthesides of the boss 14 in the bot-tom of the tank so as to hold the bottomof the carbid container at a point above the bottom of the tank, asclearly shown in the drawing. The engagement of the supports 13 with theboss 1st centers the carbid holder in the tank. The top of the carbidholder is closed by reason of the fact that the screw plug G fits snuglythereon.

15 is a pipe or other suitable conduit connected with a water supply andwith the bottom of the tank at 16, said pipe being provided withsuitable valves 17 and 1S, there being interposed between the Valves apump 19 which has direct communication with the pipe 15.

2O is a suitable handle connected to the tank 1 and to the piston rod 21of the pump.

22 is a water gage having communication with the tank 1.

23 is a cooler and purifier partially filled with water and providedwith a drier 24 which is positioned near its top.

25 is a drain valve for the purifier and cooler.

26 is a` pipe leading from the interior of the tank 1 into the coolerand purifier, thel lower end of the pipe being rebent as shown in thedrawing.

27 is a pressure gage communicating with the tank 1 and 2S is a supplypipe leading from the cooler and purifier and provided with a valve 29and a coupling 30, by means of which portable tanks may be connected forthe purpose of being charged with the gas.

The operation of my invention is as follows: The carbid holder 9 isdivided int-o a series of magazines by means ofthe removable partitions11, but before inserting these partitions, carbid is placed in thecontainer 9 until it has reached the level of the position ofthe firstpartition 11, whereupon the l partition is slid into the position shownin the drawing. Then the next magazine is filled and its uppermostpartition placed in position and so on until the tank is entirelyfilled, as shown in the drawing. The valve 29 being closed, water ispumped by means of the pump 19 through the pipe 15, past the valves 17and 18 into the tank 1, whereupon it flows through the perforations ofthe container 9 into the lowermost magazine and gas is generated fromthe carbid in such lowermostmagazine. The solid partitions 11 preventthe passage of water, by absorption, from the carbid in one magazine tothe carbid in the next magazine. As soon as all of the gas is releasedfrom the carbid in the lowermost magazine, the pump is again started andthe tank filled with water to the line shown in the drawing, whereupongas is generated from the carbid in this magazine and as soon as all ofthe gas has been generated from the carbid in the second magazine, anadditional supply of water is pumped into the tank 1 until it comes intocontact with the carbid in the third magazine and so on until the carbidin all of the magazines of the container 9 has given off its gas. Asuitable tank, for in stance one adapted to be carried by an automobile,is connected to the coupler 30 and the valve 29 is opened, whereupon thegenerated gas will flow through the purifier and cooler 23, through thedrier 24, into the pipe 28, and thence into the portable tank. As soonas the portable tank is filled, the valve 29 is closed to prevent.further escape of gas from the tank l, when the portable tank isdisconnected from the coupler 30 and placed in its position upon anautomobile.

When all of the carbid in the container 9 has been used up, all of thegas can be forced out of the tank l by entirely filling the tank 1 withwater, which enables me to lill small tanks connected to the coupler 30by hydraulic pressure to any gas pressure desired.

l/Vhat I claim is 1. An acetylene gas generator, comprising a verticallydisposed water tank having a valved drain port in the base thereof, andan internal centering boss surrounding said drain port, a verticallydisposed perforated carbid holder, divided into a series of magazinesand positioned in said tank coaXially with the drain port, a pluralityof supporting standards carried by the bottom of said carbid holder andhaving their lower ends adapted to lit snugly against the outer sides ofsaid centering boss, whereby the carbid holder is centered in the tanksubstantially as described.

2. An apparatus for producing and delivering measured charges of gas,comprising a vertically disposed tank, a carbid holder verticallydisposed in said tank and adapted to carry carbid and having means fordividing the carbid horizontally into a series of stages to produceindependent charges, and means for positively introducing into andtrapping within the tank, measured charges of water, comprising a waterpump communicating with the tank, and a check valve preventing back flowfrom the tank to said pump.

3. In a portable self contained acetylene gas generator the combinationwith a generating tank, a carbid holder in said tank, a water supplypipe leading into the bottom of the tank, check valves in said waterpipe and spaced from each other, a pump cylinder connected to and havingcommunication with the water pipe between said check Valves, a pumphandle pivotally mounted on said tank, a piston in said cylinder and apiston rod connected to said piston at its lower end and pivotallyconnected at its upper end to the pump handle intermediate its ends.

4. In an acetylene gas generator, the combination with a verticallydisposed tank having a central screw threaded opening in it-s top, of aperforated carbid holder constructed to pass through said opening intosaid tank, a screw threaded cap constructed to close said opening andseal the top end of said holder, imperforate partitions dividing theholder into a series of magazines, a port at the bottom of the tank, apipe line connected to said port at one end and to a water supply at theother end, check valves in said pipe line, a pump cylinder connected tosaid pipe line and communicating therewith intermediate said valves, apiston and piston rod in said cylinder, and a pump handle pivoted at oneend to the tank and pivoted intermediate its ends to said piston rod.

The foregoing specification signed at Gary, South Dakota, this fifteenthday of December, 1911.
